A device for dispensing fluid substances which includes a dispensing container for holding a metered amount of the fluid substance therein immediately prior to dispensing and which includes a primary opening in the top edge thereof which is adapted to be capped during filling of the dispensing container and which is adapted to be opened when it is desired that the metered amount of fluid substance should be dispensed from the container, the dispensing container also includes a secondary opening in the lower section thereof which may be substantially smaller than the primary opening, the device further includes a hollow adapter secured to the secondary opening of the dispensing chamber and adapted to be secured to the neck of a bottle or other source of the fluid substance to be dispensed, the hollow adapter including a dispensing collar adapted to be secured to the secondary opening of the dispensing container and a holder collar adapted to be secured to the neck of a bottle or holder of the fluid substance and further including a collapsible and expandable sleeve being hollow and interconnecting the two caps of the adapter to provide a path of fluid flow communication between the holder of the fluid substance and the interior of the dispensing container, the dispensing device further including a valving system within the adapter which meters the amount of fluid substance flowing into the dispensing container, the valving system may include a rubber plug member adapted to be placed within the secondary opening of the dispensing container to prevent fluid flow communication through this opening, the positioning of the plug within the secondary opening being responsive to the expanding or collapsing of the sleeve of the adapter.
